I finished drilling mount holes in the Alum-angle and
then double side taped each piece onto the acrylic side panels to
use as drilling templates. I have a set of drill bits that are
specifically for plastic and acrylic and mention it only because
they are crucial to achieving professional results when working on
stuff like this... besides, it doesn't make sense to risk cracking a
hundred dollars worth of 3/8" acrylic over a nine dollar specialty
drill bit.

Here the side panels have been drilled and are
mounted to the base for a test fit and everything so far fits good.

Below is the inner leg brace, since it fits tight
already I only need to drill out the center holes on the side edges
of the brace to permanently attach them.

The back side panel is cut from pressboard and the
first piece of the two part front panel is cut from a sheet of .220 Optix
acrylic, below shows both attached for a test fit. I also
bought a piece of black molding from a Williams wide body pinball
machine that secures the back edge of the table glass, I cut it to
size and it is sitting in place on the top edge below.

I cut the second piece of 3/16 acrylic sheet for the
front panel, below shows a top down view.

The reason the front panel had to be two sheets thick
will become apparent when I mount the speakers from the TV and the
five recessed LED buttons. The two white pieces of paper show
where I Intend to mount the TV speakers.

I had to thicken up the back material so that the
pinball table legs will seat correctly, for this I used the same
3/16" acrylic as the front panels. Sadly, in figuring out that
the thickness of the rear material mattered when mounting the legs I
destroyed two bolts and a leg mounting plate, I am currently
awaiting delivery of replacements.

I cut and rivet together a few pieces of Alum-angle
as the start of a simple mounting base for the motherboard and video card.
The four screws will secure the motherboard to the wood base of the
pinball table and the zip tie is there to hold the video card in
place.

To prevent the motherboard from ever flexing I cut and
bolt down a couple cross braces, I chose to bolt the cross braces on
instead of riveting because if the motherboard mounting holes don't
line up perfectly the bolts will adjust way easier than resetting
rivets.

I installed the processor, CPU fan, video card and memory
into the
motherboard, I also plugged in a SATA cable, an external USB and I
used an old four wire audio cable over the power switch and power LED pin-outs
on the motherboard... this thing will be ready to be mount
permanently in the cabinet after I install the OS, drivers and
software.

Next up is trying to find the best places inside the
table for the hardware. I cut and drilled a strip of 1/2"
Alum-angle and attached it to the bottom of a speed adjustable 120mm
fan, it will sit up front and blow back. Sitting just behind
the fan is a Logisys power distribution box, then the motherboard,
and behind that is the 6 outlet surge protector and the power
supply. The power supply will be ducted to the rear, as will
the subwoofer (shown still covered in plastic).

Alum-angle onto the bottom of the PSU to mount it and
a duct to the rear to provide cool air, I will probably also use
some double sided tape on the bottom of the PSU to make sure it
stays put as well as rubberize the PSU edge of the duct against
vibration.

Off with the legs! Removing the legs from the
subwoofer allows it to sit at nearly the same distance away from the
pinball table interior side wall as it sat with legs... without
interfering with a couple other things I have planned.

Below shows the three pieces of Alum-angle that I cut
to secure the subwoofer, they will all be lined with felt to prevent
vibration before the sub is final installed.

I measured out where a few holes needed to be cut in
the back panel and predrilled pilot holes using an 1/4" bit for
plastics, then I run the hole saws first forward to cut the
pressboard and then in reverse to cut through the acrylic.

Below is the back panel with the holes drilled and
the hardware that required those holes installed, everything lines
up even better than I expected. The blue-green PSU duct will
be vinyl dyed black and a black plug for the power cord was added
after realizing that the hole I cut was the exact same diameter as
the plug I had.

Next up is a look from the inside with the sub-woofer
and PSU installed, since I no longer plan to attach the six outlet
surge suppressor to the back panel I will need to figure out another
way to secure it... a fair trade for how clean the back looks.

I decided to change the design of the front panel, so
the white, green, yellow and red LED pushbuttons are now out in
favor of only using the blue LED jumbo and small pushbuttons.
Another two
small black SPST momentary pushbuttons will be recess mounted below
the plunger to act as the pause and exit to main menu buttons.

The build will now be themed totally in blue and
black, why? Because I got a really cool idea that I couldn't
shake about how to make the pinball machine really stand out visually
without resorting to print vinyl graphics. Below shows one
hundred dollars worth of blue 12v SMD LED strips in lengths from six
to forty eight inches and flavors from chaser to flashing that I
ordered from a seller in China, they will all be worked
into the project.

I had to test them all to be sure they survived
shipping so I screwed ten of them into the Logisys power
distribution box. I
really like the Logisys unit, it is made for powering video
surveillance cameras, but works perfectly for this type of
application. Also, I feel that I got more than my moneys worth of SMD LED strips, these
bad boys are wicked bright.

If anyone is curious how the active LED strips look
in action I made a video of the six inch chaser SMD LED
strips and the twenty-four inch flashing SMD LED strips...

Back to working on the front... below shows the measuring
tools, drill bits and hole saws that will be used to fabricate the
two ply
front panel.

Here are the front panel pieces almost finished, I
used the trusty Dremel flex shaft and a length of Alum-angle as a
guide for the ripsaw blade to cut out the extra bits from the
speaker holes.

The front panel with the speakers, buttons and
plunger test fit, I still need to cut some mesh and install it over
where the speakers are going to sit.

I got the mesh for the speaker holes cut and test fit, when it comes time
for the mesh final install I will secure it in place with Weld-on
16.

I took the front, table sides and back glass sides to
my little brother to sandblast the back of the acrylic panels where the SMD LEDs
will be located.

I designed an old school looking graphic for the
project, my brother has a vinyl cutter so while I was there I
also had him cut me some decals...

Weeding vinyl sucks, for those who don't know -
weeding is the removal of scrap vinyl that will not be part of the
final decal and it is a tedious process. I used clear contact
paper over the weeded vinyl so that they can be lifted off the paper
backing and installed onto the acrylic. Below are three of the
decals I will be using as masks for the vinyl dye part of the
project.

Below shows placement of one of the vinyl decals, it
also shows placement of the four 6" SMD chaser LEDs. The plexi-glass
where the LEDs sit has a frosted look after sand blasting and should
diffuse the blue glow a little when the LEDs are installed behind
it.

I needed something to install the 6" chaser LEDs onto
so I copied my measurements onto a piece of aluminum flashing, then
cut and
rivet it onto the front brace piece of Alum-angle.

The four 6" SMD chaser LEDs all had short bare leads,
so I soldered them all together and added longer wires, then I
sleeved and heat shrink the whole thing. Now it will only need
a single power output from the Logisys power distribution box and
even though sleeving was unnecessary because it will likely never be
seen it does look nice.

I assembled the router table that sat in my
shed forever and loaded it with an 1/8" roundover bit in
preparation for this next part.

Wow, what a plastic dust making mess... note to self,
next time do it outside. I rounded off the edges of the front
and sides, it all feels nice and smooth now.

I wasn't real happy with the lack of picture
adjustment that the USB 16" monitor had and the viewing angle was
terrible. Below is the VGA model, it is fully adjustable, VESA
mountable and the viewing angle is acceptable.

The two screens are almost exactly the same size,
which is required for the project to turn out correctly.

Below shows an Antec EarthWatts 750 PSU, a white
lazer LED, two sound control modules and four super bright 24 white
LED strips. They will be used to power and help light up the
replacement parts that are coming from the pinball projects first
